Don't really need to. It's a negative ground system so just use the engine as ground. If you really want to get to the battery post the top is not too difficult to remove. Did it to replace battery a few years ago but don't recall the details.

Battery voltage alone won't tell you its condition. It needs a proper drop test to check cranking amps.

rensho so you just connect the neg to any solid part of the engine , and it is the same as connecting to the neg post mate

remember you are looking for 13v ideally from a good battery and about 14.3v charging.

Yes, any metal part attached to the block should do the trick.

Battery voltage .... look here .. http://www.mmbalmainauto.com.au/PDF/Stat...teries.pdf

Details are for lead acid types but a more modern battery will be within a small % difference

I use the stud on the inner wing that I presume is there for this purpose. I charge through that with a smart charger too, works prefect.
